Open the CIPO recordAbstract From the Canadian patent
The present invention provides a method of magnetic resonance imaging of a sample, said method comprising: administering a hyperpolarised MR imaging agent comprising non-zero nuclear spin nuclei into said sample; exposing said sample to a radiation at a frequency selected to excite nuclear spin transitions in said non-zero nuclear spin nuclei; detecting MR signals from said sample utilising spectral-spatial excitation in combination with line , scanning, point scanning and/or steady state imaging techniques; and optionally generating an image, physiological data or metabolic data from said detected signals.

Why it's free to use
- Filed September 12, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 12, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 12, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
